Be it known that l, MELVILLE CLARK, a

' citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Vehicle Wheel-l1res, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose ofthis invention is to provide an improved construction of a vehicle wheel adapted to have a pneumatic air cushiontire particularly in respect to the guards between which such cushion or pneumatic tire is retained upon the felly.

It consists in the elements and features of construction shown and described as indlcated in the claims.

In the drawings :-Figure 1 is an outer side elevation of a segment of a wheel embodying this invention.

p is a section at the line, 3,-3, on Fig. 1, upon an enlarged scale. Fig. l is a section at the line, 4,-4, on- Fig. 1.

This invention is shown as applied to a wheel having a tread member retainedon the wheel between lateral metal guards which are clamped upon the felly. The pneumatic and cushion elements of the tread member are shown only in general cross sectional outline, detail features involved in the invention being suppressed or omitted.

1 represents the folly of a wheel upon which there are clamped the lateral guards,

' 2 and 3, between which the cushion tread 'member, 4, and the pneumatic tube,

' thevtire are retained.

The guards, 2 and 3, are shown as having circumferential inturned flanges, 3, of hook-form in cross section for engaging circumferential ribs or I beads, of the tread member, l, of the tire.

'lhe specific purpose of the invention is to facilitate the removal and application of the outer guard member, 3, for inserting and removing the cushion and pneumatic tread members, 4 and 5, or for obtaining access L0 those members for any attention which they may require; and specifically, to facilitate such removal of the outer guard member without removing or even releasing or loosening the inner guard member. To this end there are provided at frequent intervals in th circumference of the wheel interiorly 6, each having at Specification at Ectters Patent.

into the outer lateral side ofthe folly which is bored to receive them and counter-bored to receive the flanges, 6*, the eountenborc being deep enough to provide a cavity outside the flange when the socket is fully in-. serted to accommodate the flange, 7, of a bolt, 7, which is threaded for screwing into the socket and which has a head, 7, immediately back of which the flange, 7, is formed, said head being adapted for engagement to rotate the bolt, being for this purpose, as shown in the drawings, square in cross-section, the length of the head from the flange being: sufiicient to cause it to protrude thrqugh the thickness of the outer guard member sufficiently for engagement of a key or wrench by which it may be ro-- tated. The socket, 6, is clamped firmly into the telly by means of .a headed bolt, 8, set

through the felly from the opposite side and screwed into the inner end of the socket. Preferably this headed bolt, 8,v is set through the inner guard member so that its head stops upon the outside of the latter and serves to bind said inner guard member onto the feliy while clamping the socket, 6, securely thereto. As a precaution against rotatability of the socket, 6, this flange, 6*, may be provided with one or more countersunk apertures through which I screws or nails, 9, with countersunk heads are set into the felly with the heads flush with the outer face of the flange. If preferred, the flange, (3 may be furnished with a circumferential cylindrical. flange, 6, making it as a whole cup shaped with a cavity sufiicient to accommodate the thickness of the flange, 7*, of the bolt, 7. The outer guard member, 3, is clamped onto the felly by means of head'- ed bolts, 10, set through it from the outer side and through the felly which is bored to receive them, and screwed into sockets, 11, which are set into the felly from the inner side and provided with heads, 11, to accommodate which the apertures in the telly which receive the so'ckets are counterbored at the inner side. By screwing up the x..bolt.s, 10, into the sockets, it will be seen that the telly and outer guardmember 3, are chhnped between the bolt heads and the socket nut heads, securely on the felly.

To apply the outer guard 3, to the felly the flange bolts, 7, will he first screwed into the sockets, 6, then the guard will be applied one end a flange, 6, these sockets being set I to the folly, the heads, 7, of the bolts being thus holding said guard flanges, 3*, of the guard arev pressed quite forcibly against the lateral flanges, 4:, of the cushion tread member, and then before fully tightening up the bolts, 10, by rapping smartly upon the tread member at different points in the circumference, the flanges, P, will be caused to spring into engagement with the flanges, of the guard throughout'the entire circuni erence, of the Wheel, and the bolts 10, may then be tightened up fully. member, the bolts, 10, will first be withdrawn and then, by means of a suitable wrench or key to unscrew the bolts from the sockets,- 6, the flanges, 7 will be caused to crowd the guard outwardly" until the lateral flange, 4 of the cushion tread member springs out of engagement with the inwardly hooked flange, 3, leaving the guard entirely free. If deemed desirable for greater security of attachment of the inner guard member, 2, lag bolts, 12, mafy be employed inaddition to the bolts, 8, or securing it to the telly.

1. In a vehicle wheel, in combination with the folly, metal guards bound onto the opposite sides of the folly for retaining a tread member between them; means for clamping the guards onto the telly, and means for forcing one of the guards off the felly, consisting of interiorly threaded sockets mounted in thefellyrbolts threaded-for screwin into the sockets having each a head a apted for engagement for rotating it and a transverse flange back of the head,

, 2. In a vehicle wheel, in combination with the folly, lateral guards bound onto opposite sides of the felly for retaining a tread member; means for clamping the lateral guards onto the folly and means for forcing one of the guards ofi'the felly, said last mentioned means consisting of a multiplicity of devices distributed over the entire circumference of the folly, each comprising an in teriorly threaded socket having a flange head and set into the telly from the outer side, the fellv being bored to-receive it and counter-bored to receive the flange, a headed bolt set into the folly from theopposite side andscrewed into the inner end of the socket For removing the outer guard by rotating the bolts, 7,-

of the bolts having a head adapted to be engaged for rotating it, and a transverse flange back of the I dated in the counter-bore which receives the socket flange, the outer guard being apertured to permit said bolt head to protrude for engagement of a rotating means, the inner guard being apertured to receive the other bolt, and said other bolthaving a head for engaging outside said inner guard, and means for clamping the outerguard onto the folly.

4. In a vehicle wheel, in combination with the folly, metal guards bound ontothe opp for retaining a tread member between them the guards onto the folly, and means'for forcing onset the guards ofi' the felly, consisting of interiorly threaded sockets mounted in the folly; bolts threaded for screwing into the sockets each having a head adapted for engagement fort rotating it and a trans verse flange back of the head through which the head protrudes for exterior engagement to rotate it, themeansfor clamping the outer guard to the folly consisting of interiorly threaded sockets headed at one end set into the inner side of th folly and headed bolts set through the outer guard and into the folly and screwed into said sckets.
